Answers:
Area = 254.34 square feet
Circumference = 56.52 feet
=========================================================
Work Shown:
Area = pi*(radius)^2
A = pi*r^2
A = 3.14*9^2
A = 254.34 square feet
----------------
Circumference = 2*pi*(radius)
C = 2*pi*r
C = 2*3.14*9
C = 56.52 feet
The two results are approximate since pi = 3.14 is approximate.

Answer:
(x+1)2+(y−2)2=5
Explanation:
The general form for a circle with center
(a,b) and radius r is XXX(x−a)2+(y−b)2=r2
With center (−1,2) and given that (0,0) is a solution (i.e. a point on the circle),according to the Pythagorean Theorem: XXX r 2=(−1−0)2+(2−0)2=5
and since the center is (a,b)=(−1,2)by applying the general formula we get:XXX(x+1)+(y−2)2=5
